That is what I was thinking, put a metal door on a concrete wall and have the police try and waste their time on that while you get away through a escape tunnel.
Pro-tip: it's not just about the door; it's about reinforcing the hinges and striker plate. Even if you're not the kind of person who expects a SWAT team to show up, you want to make sure those things have 3-inch screws going into the wall studs, not just little short screws going into the door frame.
Honestly, I was wondering the same thing before I posted this. I think it's from another gif.
Have you seen the one where a Russian dude is about to fully close his door to the Russian police in the apartment hallway, but he decides to call them bitches or the like?
